PWM to Voltage Converter Module 0-10V Analog Transmitter

The PWM to Voltage Converter Module is a highly efficient signal conversion board designed to translate digital PWM (Pulse Width Modulation) signals into a stable analog voltage output ranging from 0V to 10V. This module solves the common engineering challenge of interfacing microcontrollers, which output digital PWM signals, with industrial equipment such as Variable Frequency Drives (VFDs), PLCs, and motor speed controllers that require standard 0-10V analog control inputs.

Featuring onboard optocoupler isolation, this module ensures complete electrical separation between your sensitive control circuitry (like Arduino, ESP32, or Raspberry Pi) and high-voltage industrial power systems, preventing electrical noise and ground loops. The onboard multi-turn precision potentiometer allows for easy calibration, ensuring that a 100% PWM duty cycle corresponds precisely to a 10V analog output. It is highly reliable, compact, and an essential tool for industrial automation, CNC spindle speed control, and custom DAQ systems.

Features:

• Optocoupler Isolation: Provides excellent electrical isolation to protect microcontrollers from industrial electrical noise.
• Wide Operating Voltage: Supports a power supply input range of 12V to 30V DC (at least 15V is recommended for a full 10V output).
• Dual PWM Input Levels: Easily configurable to accept 4.5V to 10V (MCU level) or 12V to 24V (PLC level) PWM signals via an onboard jumper.
• Precision Calibration: Equipped with a multi-turn trim potentiometer for fine-tuning the analog output voltage.
• Linear Conversion: Converts 0% to 100% PWM duty cycle linearly to 0V to 10V analog output.
• Compact and Lightweight: Weighing only 12 grams, it is easy to integrate into tight control enclosures and custom PCBs.
